A Nene valley town at a busy junction
Thrapston is a small market town on the River Nene, where the A14 meets the A605, with Islip just across the medieval bridge.
Lakes from old gravel workings line the valley, and the junction has attracted large distribution and industrial buildings. North along the Nene, the stone villages lead to Oundle, with its limestone streets, and on to Fotheringhay and Elton.
So one week it’s movement joints on a warehouse, the next it’s a window in a stone cottage: two very different jobs that both need the right sealant.

Movement joints that can really move
Big buildings expand and contract a lot, and their movement joints have to take it without tearing. We size backer rod to the joint, prime where required and use low-modulus sealant designed for the movement.
- Brick, block, precast and concrete joints
- Cladding, coping and door-frame joints
- Boom lifts, towers or scaffold
